Central European Summer Time (CEST, UTC+02:00), sometimes referred to as Central European Daylight Time (CEDT),[1] is the standard clock time observed during the period of summer daylight-saving in those European countries which observe Central European Time (CET; UTC+01:00) during the other part of the year.
[2] Other names which have been applied to Central European Summer Time are Middle European Summer Time (MEST),[3] Central European Daylight Saving Time (CEDT),[4] and Bravo Time (after the second letter of the NATO phonetic alphabet).
[5] Since 1996, European Summer Time has been observed between 01:00 UTC (02:00 CET and 03:00 CEST) on the last Sunday of March, and 01:00 UTC on the last Sunday of October; previously the rules were not uniform across the European Union.
[6] There were proposals to abandon summer time in Europe from 2021, possibly by moving winter time up by an hour and keeping that time through the year.
